I think double click would be even better. Because I had trouble finding it out myself too.And placing the second click on time is kinda hard since you don't know how long you have to wait, and even if you got it right you'll still notice a delay before it does what it has to do, making you think it didn't work.So definitely something I'd like to see improved too.

How do you use this new categories option? If I right click a download, I have an option on the context menu saying "set category" but it does nothing when I click it. No signed of categories.abz in my alt.binz folder either... Am I missing something here?

Make sure you have the new 0.36.0 (guess you already have that). Setup -> Download (The first one) -> Categories, the button underneath the Default download folder path box.
